BUG/MINOR: tcpheck: the source list must be a const in dup_tcpcheck_var()

Browse Source 
This is just an API bug but it's annoying when trying to tidy the code.
The source list passed in argument must be a const and not a variable,
as it's typically the list head from a default proxy and must obviously
not be modified by the function. No backport is needed as it only impacts
new code.
